Can detonation shock scale from your cylinder walls? My new radiator is already clogged with scale from my block and it seems to have happened ever since I heard some detonation pulling a steep hill. It was a 90 degree day and that may have contributed to the detonation. The block has been in the car for about 6 years now so this isn't a new build so the scale in the radiator was somewhat of a mystery to me.
I am going to flush the block and install an inline filter in the upper hose for a while and see what it catches.
